I understand that flourscent yellow green is the most visable to the human eye in bright daylight. As it turns to night orange/red become more visable as color vision is reduced in dim lighting. This has to do with the ratio of rods and cones in the human eyes. We lose night vision to gain color vision in the daylight compared to most animals who have limited or no color vision.
So my question is I need to buy some rubber caps to cover grease Zerk fittings. This will help keep them clean and make them easier to find. I would suppose that there is a better choice then black so they will stand out in dim light covered with some oil and grease. Choices run black, blue, yellow, green, red and black. The idea is easier to find color will help me make sure I grease them all under a car or machine. Yes I could use a map and check system to make sure I hit them all.
I realize this may seem like a simple question. Ia m just wondering if anyone has studied this effect. I have read that any choice of reading material othe then black on white has at best 80% readability. Some color choices are over 50 % harder to read due to lack of contrast,.
I do know that red green color blindness is the most commom one. Many cars used red or green led dashboards until makers realized blue was a better choice for male drivers. That also means red/green traffic lights are about the worst possible choice. This is the reason red firetrucks have switched to lime green. Of course men are far more likely to be colorblind then women drivers.

This is prtobaly a mote point with them covered in dirt and grease with none of the actual object visible.
